TO ALL WHOM IT MAY OONCERN:

Be it known that Il, ANDREW HARTMAN, ot' Canton, vin the county of Stai'k, and State o1' Ohio, have invented certain new and useful Improvements inRailroad Switches; and do hereby declare that the following is a full, clear, and exact descriptionthercof, reference being` had to thc accompanying drawings, and to the letters oi' reference marked thereon, making a part of this specification. i

Figure 1 represents a plan view of the railroad switch.

Figure 2, a section of the same through line z x, fig. 1.

Figure 3, a side view with the car and device attached thereto for operating the switch.

y In the annexed drawings, A represents the main track, which is connected by a bar, a, near the switch. B B arc the rails of theside track, and stationary, while the rails AA of main track are movable. At one side of the track, and about one rails length apart each side of the switch, are L -shaped levers, which are pivotedu toa board or plate at the point where they are bent,and so placed that when in their natural positions the longest end lies directly against the main track at one end, D, and the side track at the other, D. E represents a triangular-shaped plate, lying about one half way between the two levers D D', -and which is pivoted at 1c. Extendingfrom the outer and inner points of this plate are rods d d, which connect-to the outer ends of levers D and D respectively. The other point is connected to the rail by means ofI a rodfW, and readily draws the track back or forth when the levers are operated. b isa curved metal bar, which lies between the rails A A, l

and, by means of prongs and small. openings in the track, passes through it at both sides. At the side opposite the levers, and suspended under the bar b, is a weight, m, pivoted to andattached to a trigger, n, which -extends just beyond the rail, and between the prongs of the bar b. Suspended from saidbar, slightly beyond the weight m, is a tumbler, g, which is operated by means' of a rod, o, connected to the opposite rail. S represents a coil spring placed within a metaly case near the plate E at the outside of the rails, so that when the track is drawn 'from the main to the sideling, and not held there, the aforesaid spring will recoil and force the track to its natural place.

` It will be observed that whenever the track is drawn to the sideling', that rod o turns the tumbler g, thereby releasing the weight m, which falls and causes the trigger n to come up and secure the track. Pivoted to the outside ofthe track is an eccentric, C, which is just over the end of the trigger, and which is operated by the locomotive. F representsa car, showing the devices which are connected to the locomotive and hindmost car for operating 'the' switch. The attachment for the locomotive is shown at l, which is a hand upright lever which elevates a rod or lowers it, which is connected to an L-shaped bar for 'raising or lowering -a shoe, q. When nearing the switch the shoe is lowered, and forces the eccentric upon and operates the trigger, causing the switching of .the rails. p J/ Having thus fully described my invention, what I claim as new, and desire l ,-cure by Letters Patent, is

.In an automatic switch the arrangement of the plate b with tumbler g,/ ,nt m, trigger n, and spring s, operated by the shoe g and eccentric C, connected to the railroad car and/ respectively, lwhen used in combination with the plate E, levers D D', (connected by the rods 62,) and operating in the manner substantially as v specified.

As evidence that I claim the foregoing I have hereunto set my hand in the presence of two witnesses. ANDREW HARTMAN.
